Mixing Motor Oils

Lin · September 17, 2016, 09:38:29 AM

I had recently switched from Delo 100 to Delvac 1240. In going through my stock, I find that I have 3 gallons of Delo 100 left. Can I use that to top off the Delvac should I need it?

you can mix tractor supply oil or Walmart oil or Rotella or whatever.

Delvac is not magic

Pour what ever you choose Lin then watch your oil consumption go up

Cliff, as mentioned in an earlier thread, my oil consumption dropped significantly when I did the change, so I assume that using the Delo will increase it somewhat. However, I just find it hard to toss 3 gallons of new oil. I thought that if they are compatible, I could let the engine burn through them. Maybe someone on Craigslist would want them.

I recently changed from straight delo 100 40 wt to the Canadian Walmart straight 40 wt CF2 - 5 gal & Lucas full synthetic oil stabilizer - 1 gal which puts it right to the full mark on the dipstick. I added five quarts of delo 100 40 wt after 4800 miles to bring it back to full on the dipstick. Best (least) oil consumption our coach has shown us in many years and better oil pressure across all rpms... Go figure! Some Canada Walmarts sell the Cf2 oil in 5 gal pails for $58.
Come on USA, catch up already!

Thread drift alert: anything wrong with 50 weight?

After this last week most of any excess oil we had is on the front of RJ's Bus from caravaning up to the Washington Rally. Sorry Russ at least it won't rust.

Nothing wrong with 50 wt, as clarences increase & oil pressure decreases 50wt becomes an option. Don't think our engine is there yet.

Read the book DD calls for 50w in certain conditions like the temp of 100*+ we get here in AZ I have a couple of generators I look after that run around 200* and it calls for 50W too

Harley Davidson's have been using 50 and 60 weight oils way way before Detroit two strokes..>>>Dan

You all got me thinking ... What would be the minimum temp you'd run 50 in DC? Got a block heater anyway. Just wondering.

Delo 100 has less ash content than Delvac, it's good enough to keep for adding. Yes, Delvac 1240 is good, but I don't know about it being the Cadillac of oils. If it was really that good it might be better to say it was the Mercedes Benz of oils.

LOL you don't see the Detroit name or spinning arrows on Delo 100, Mercedes Benz of oils will work
